STOVB-PIPE SHELF.

TO ALL WHOM IT MAY CONGERN: i

Be it knewnthat I, H. C. JOIINsoN, of Delavan, countyr of Walworth, andState of Wisconsin, have invented a new and useful Improvement inStove-Pipe Shelves', and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilled inthe art to Ineke and-aise thc samc,`rcl`erence being had tothe accompanying,d1-owing, forming partof this specification, inwhich-r1- Figur-c l is a perspective view of the shelf` attached to thestove-pipc, with one of the leaves turned up.

Similar letters of reference, in each of the figures,indicatecorrespondiug parts.

The object of my invention is to provide a shelf, forming a table, withlcavcsyou which anything can b placed which it is desired to keep warm,and attaching the same to a stove-pipe.

I make this shelf .of any suitable metal, and usually with interstices,to make it light andsymmetlicalt A A is a-stove-pipe; 'B and B', thecentre shelf, made of two pieces, as shown, figs. 2 and 3, with acollar, (projecting above and below its upper and lower face,) whichcneloses the pipeA, as shown, fig..1. C and C', side leaves; D, narrowloops on the sides of the centre shelf; E, wide loops on the sides ofthe centre shelf. These loops are placed, one narrow and one wide, oneach of the pieces B and B. F, Vhooks on the 'leaves Cv and C. Thesehooks, 'on theirvunder sides, have a semicircle projection, which, whenthe leaves are turned up, 4asC' is 4show-n in iig. 1, rests ou theoutside ofthe loops D and E, and, as the leaves are turned down, theseprojections turn on the loops, casing the leaves down, and preventingconcussion. .The points of the hooks F, passing under the centre shelf,form a. support, which keeps the leaves in position, even, and on aplane with the centre shelf. G, hooks on the partsB and B of the centreshelf, which, when the two parts are brought together, the point ofeachhook.passes under the opposite piece B- or B', forming a mortiseon eachside Ao t the centre shelf, -for a keyto be driven, to hold the parts Band B"together, and make them hug the stovepipev firmly.v lhcsehooks G,when the parts B and B are tog-ether, have a. leverage on the parts,which, when one end of the shelf is held, the other cannot fall or hepressed'dpwn, whilst, on lifting on the outer ends of B and B, they,will double up together. H, keys, which, when driven into the mortisemade by hooks G, hold the centre shelf B and B firmly together. I,hoolrson the corners ofthe centre shelf, on which to hang anything, asdesired, and also to ferm e rcleaf should the stove-pipe be so large asto prevent the two parts B and B from coming close together, in whichease the l-eavcs would not he long enough to come out flush withthe'e'n'ds of the pieces B and B'. Thatthe leaves maynot be cramped insuch a. case, one loop on cach side of the centre shelf is wider thanthe hoolcs on the side ofthe leaves.` These pieces B and B/ aremade bothalike, as also tho leavesv C and C', so that, should any one get broken,any other one will fit in its plac.

Operation: To put up the shelf, take one of the pieces B in one hand;place its recessed end against the stovepipc; then take the other pieceB in the other hand, and hring'i'ts recessed end to the other side ofthe stovea pipe, passing the hooks G under each pioeeB.. Then let gowith one hand', and with it put in the keys H, and drive them into themortises made by hooks Gr, and the pieces B and B will he made to hugthepipe A closely, und remain firmly in position. Then place the leaves Cand C one on each side, their hooks F passing into loopsJ) and E, whichwill hold the leaves in position. i

What I claim as my invention, and desire to secure hy Letters Patent, is

1. '.'A stove-pipe shelf, when made lin pieces B and B', with leaves Carid-G. secured ,to a. stove-pipe', substantialllyas described. I l

2. Loops Dand E, i'n combination with hooks F, to secure leaves C and Cto the centre shelf B and B',

instructed as described, one loop being Wide, and the other no1-row,oneuch-piece B, to provide for the parts B and B being-adjusted.

3. Forming hooks F straight on top, and with the semicircle projectionon the Bottom, as described, for the purpose of easing down the1eaf,.and holdingvit -in place. v H. C. JOHNSON,
